I'm sending an object back to express that needs to be printed via escpos (for a thermal printer on Ubuntu 18).

My front end server is react.

I need to print 'receipts' for information that can be of a variety of object after the first set of variables

date
name
customer name
customer phone
[array of objects]

I can create a route for the first set of vars

router.post('/printer/:date/:name/:custName/:custPhone/', function(req,res,next) {

But is it possible to add to that route dynamically for object that can be various such as:

 type: 'pizza', drinks : '2' 

or

 extra : 'garlic bread' 

I current send the data back like this in the front end:

axios.post('/api/printer/' + newDate + '/' + userName + '/' + selectedCustomerName + '/' + selectedCustomerPhone)

I've considered posting such as this:

 axios.post('/api/printer', 
 name : userName,
 date : newDate,
 customerName : selectedCustomerName,
 customerPhone: selectedCustomerPhone,
 type : orderType,
 extra : orderExtra,
 drink : orderDrink
 )

and then grabbing it in Express, parsing for information and then sending to the printer seem's the most local way.

I was curious if a method with a 'dynamic' route is possible otherwise?

You don't need to set all the needed variables as route params. You should put them all in the request body like you 'considered' to do.

Then at the server:

app.use(express.urlencoded(extended: true));

router.post('/printer', function(req, res) 

 const data = req.body;
 console.log(data)

 //Do what ever you want 

 res.send('OK')
